Effects of resveratrol (RES) and genistein (GEN) on spontaneous phasic contractions. Typical recordings after administration of the solvent DMSO (A,E), RES (B) or GEN (F); the tension (C,G) and the mean amplitude (D,H) of the uterine contractions are shown after treatments with different drugs such as β adrenoceptor antagonist propranolol (PRO) and ICI118551, ATP-dependent K+ channel blocker glibenclamide (HB-419) and NO synthase inhibitor N-nitro-L-arginine (L-NNA). * p < 0.05; ** p < 0.01; *** p < 0.001; vs. control group (the value is set as zero). +
p < 0.05; ++
p < 0.01; +++
p < 0.001; vs. RES or GEN group.
